You have short circuit. I think you should not use Sunroof until repair the your cable.

As I though you have to make some operation the cables which are located behind of the Sunroof Button…

u can also check your battery ground to see if it’s making good ground contact…

You have a grounding issue. Make sure your engine is grounded.
